BCI-2000 bci2000 Unibus Adapter for the PCI Bus _________________________________________________________________ The BCI-2000 Unibus Adapter enables Unibus devices to be connected to workstations supporting the PCI bus. The BCI-2000 supports both PIO and DMA Unibus data transfers as well as providing support for all four Unibus interrupt levels. The BCI-2000 consists of a single slot PCI controller, a dual-width Unibus cable adapter module, and an eight-foot shielded interconnect cable. The PCI controller occupies a single PCI slot. The Unibus cable adapter installs into the Unibus connectors A and B of an expansion chassis or user's equipment, replacing a Unibus cable. The BCI-2000 provides complete support for: * Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. * Unibus DMA data transfers including read word, write word, and write byte. * All four Unibus interrupt levels: BR4, BR5, BR6, and BR7. _________________________________________________________________ Features Provides a migration path. The BCI-2000 allows users of Unibus systems to migrate to the new high performance PCI workstations and retain their existing Unibus I/O devices without loss of function or performance. High performance. Unibus PIO and DMA data transfers occur at maximum Unibus speeds -- throughput is limited only by the Unibus device. Cost savings. The BCI-2000 provides users the choice of low cost, high performance PCI workstations while retaining their existing investments in Unibus hardware and software. Easy to install. The BCI-2000 allows multiple I/O devices to be connected to a workstation while occupying only a single PCI-slot. Easy to maintain. The BCI-2000 executes a comprehensive set of diagnostics to automatically verify module operation. _________________________________________________________________ Description PIO Transfers The BCI-2000 supports the four types of Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. The entire Unibus address space is available for access by a PCI host. DMA Transfers The BCI-2000 provides full compatibility with the three types of Unibus DMA data transfers, including word read, write word and, write byte. Single and multiple data transfers are supported. Interrupts The BCI-2000 passes Unibus interrupts to the host for service if interrupts are enabled by the host and the interrupts are higher priority than the priority established under software control. The BCI-2000 stores the 8-bit interrupt vector in an internal register that is referenced by the host to determine the interrupt service requested. Unibus Termination The BCI-2000 provides Unibus termination for one end of the Unibus. The user must ensure the Unibus is terminated at the end of the Unibus within the expansion chassis or the user's equipment. Unibus Parity Unibus parity signals PA and PB are terminated but otherwise not supported by the BCI-2000. _________________________________________________________________ Software Compatibility The BCI-2000 is not supported under existing OpenVMS, Ultrix, or OSF/1 operating system software and requires software drivers to support the features offered bu the BCI-2000.
